In this we have introduced the application of even formula in making certain equivalent double electrons′ atomic states and the generic way of making certain non-equivalent double electrons′ atomic states,and have got the quantificational connection between atomic states′ number and atomic orbital azimuthally quantum number.

偶数定则是确定非同科双电子形成的原子态的一般方法，根据偶数定则得到了二价原子的原子态数与原子轨道角量子数之间的定量关系；并用数学归纳法证明了有关结论。

This kind of material is had volatile, after the evaporate in alkalescent solution goes out, with titrate of standard acerbity solution, computation its content. Triumphant family name decides 1.2 main instruments and reagent azotic appearance: KJeltecTM2300,; of Swiss FOSS company magnesian, boric acid, hydrochloric acid: The? that treat Ju is magnesian mix hang fluid: 1%.

It is proved that the dual time step algorithm is efficient in the simulation of unsteady flow with the prediction of vortex shedding over circular cylinders and shock buffeting over bicircular airfoils.

在非定常流动的数值模拟中引入隐式双重时间步方法，并对2种经典的非定常流动现象进行计算，取得令人满意的结果，证明双重时间步方法具有较好的精度和较快的收敛速度。

This was a female adult case of severe bimaxillary dental alveolar protrusion and open bite. Fortunately, it was not combined with bimaxillary prognathism and her skeletal relation is neutral, no Class Ⅱor Class Ⅲ feature was noted.

&锚定控制&在治疗严重上下颚前突的病例中是非常重要的工作，虽然现在已有微植体的植入可以帮忙达到理想中的&绝对锚定&，但对患者而言，再简单的手术都有风险及压力。

Methods We searched PubMed, Blackwell, BIOSIS Preview, The Cochrane Library, VIP and CNKI electronically from January 1, 2000 to April, 2008. Relevant journals and conference proceedings were also handsearched. Randomized controlled trials and quasi-RCTs comparing desloratadine with other medicines in the patients with CIU were considered eligible.

以地氯雷他定和慢性荨麻疹为检索词计算机检索从2000年1月到20008年4月的Cochrane 图书馆、PubMed、 BIOSIS Preview、BlackWell、VIP、CNKI等数据库，收集国内外所有关于地氯雷他定治疗慢性荨麻疹的随机对照试验，并手工检索相关杂志。

Starting from boldine (56), secoboldine (57) was prepared by ring opening at N6 position. Then the resulting secondary amine, secoboldine (57), was treated with various substituted benzaldehydes, to form a series of diarybutanoid-like tertiary amine alkaloids.

以波尔定碱(boldine， 56)做起始物，在N 6位置做开环反应可以得到次波尔定碱(secoboldine， 57)，再用还原胺化反应在二级胺上接上不同的苯醛，可以得到一系列的三级胺生物碱化合物。

A mixed indicator composed of bromocresol green, methyl red and phenalphthalein was used as indicator in titration of boron after the inteterience of cobalt was masked by EDTA.

采用甘露醇强化硼酸滴定硼时，以EDTA为掩蔽剂，可消除二价钴对硼分析的干扰；改用溴甲酚绿-甲基红-酚酞三元混合指示剂作为测定硼的指示剂，使滴定终点灵敏，准确。

Just prior to the analysis, prep a re the test solution by adding 0.5ml of the bromophenol blue indicator solution to each 100ml of the aqueous acetone solution and titrating with 0.01 N HCl or 0.01 N NaOH until the test solution is just yellow in color.

分析前准备好测试溶剂，100ml含2%水的丙酮加到锥形瓶中，加0.5ml 1%溴酚蓝水溶液指示剂，用0.01N NaOH溶液滴定至绿色或蓝色，然后用0.01N 盐酸标准溶液滴定至刚好呈黄色
